Does Your Shampoo Have the New "It" Ingredients?

Discover the new crop of hair care products with cutting-edge ingredients

Stem Cells First things first: there are two types of stem cells. Human-derived and plant-derived. Human stem cells carry a host of ethical questions, plant-derived stem cells may not do much at all (depending on which expert you talk to). However, if they're doing what they're supposed to do, both varieties of stem cells trigger your skin cells to regenerate more quickly and act like younger cells.

According to biologist Paul Knoepfler at the Univeristy of California Davis School of Medicine, eventually stem cells will be used to cure baldness. "Research on specialized stem cells that can grow hair has been advancing at a rapid clip," he says. But we're not there yet.

In the meantime, products like Julien Farel Restore, $33, contain plant stem cells, hyaluronic acid, and antioxidants to protect and hydrate the scalp and help you grow healthier hair.
